When
Avril Lavigne and Chad Kroeger announced their separation in September, they vowed to be "the best of friends" and it appears they are staying true to their word. On Sunday night (Feb. 14), the Canadian singers attended Clive Davis' annual pre-GRAMMY bash together, proving that there are no hard feelings between the former spouses.

Avril, who is on the mend following
months of treatment for Lyme disease, looked healthy and happy as she strolled the red carpet in a fun and flirty black lace gown. Her former husband looked equally dashing in a black suit. Inside the event, the Napanee native and Nickelback frontman dined with rock and roll royalty, including Alice Cooper and KISS members Gene Simmons and Paul Stanley. Avril later shared pictures on Instagram from her "lovely night."

This isn't the first time that Avril and Chad have spent time together post their split. They have frequently
collaborated on music for Avril's upcoming fifth album and have been spotted together out and about in Los Angeles. And while their appearance at Clive's party appears to be rooted in friendship, a reconciliation between the two could be in the works as it appears both stars are currently single. Avril has been spending time with musician Ryan Cabrera but the singer has yet to confirm if they are dating. Only time will tell if the duo decide to give their love story another chapter!
